To be honest, I have no experience with coin acceptors, nor cctalk, but I feel confident I could do this project.
However, I will need an online session with you to discuss the details of this project and then to adjust my offer to a more realistic one.
About me, I am a senior SW developer, with whole my 6 year experience in automotive industry, and I am from Romania.
If you want, we can collaborate for this project.
